what you describe is what's called 'svo' [straight veg oil] in
bio-speak.  biodiesel specifically refers to veg oil that's been
trans-esterified with ethanol from a triglyceride [eg. fat] to lighter
[mono-]ethanides, liberating glycerol in the process.  the most common
homebrew approach is a multi-step process that uses lye as a catalyst
and -very-dry- alcohol, as water at that point poisons the reaction.
today the glycerol is just dumped, but in large scale new uses would
have to be found for it.

svo does need to be heated to about coolant temps to pump, inject, and
combust properly.  biodiesel is light and thin enough to work as-is.
you -can- just pour it into the tank and go.  likewise it just works
in furnace and water heater oil burners ['bioheat'].

heated svo works well and would be a good solution for diesels that
run 24x7 or have a high duty cycle, or have some alternate way of
heating the fuel when the engine isn't running.  this isn't very
practical for those of us who want to be able to jump in the car and
go.  biodiesel doesn't need to be heated, but pure b100 [100%
biodiesel] starts to solidify at not much below freezing.  this is its
weakest point.  the present winter solution is a b20 blend - 20%
biodiesel / 80% petrodiesel.

over in england the homebrewers run b99.  inland revenue want their
road tax, and the 1% petrodiesel satisfies the letter of the law...
